Ir a 9070 pro e 021 0101/0102

[worthy67]

Hi hope somebody can help

we installed a 9070 pro just under 3 weeks ago customer has done just over
40k .
We have already had to replace magenta & yellow dev assy due to rear of devs starved of dev thus getting deletions at rear of copies.
New devs sorted this but now we have another problem.
On checking the error history e021 had been happening before the dev problem.
Sub codes 0101/0102 .
Strange thing is if customer is using paper deck sra3 160gsm coated stock
the machine after a couple of copies errors but if you use any of the other cassettes it works fine and does not error at all .
Obviously you cant selct coated stock through the cassettes but if you put the coated in or any other stock no problems ,

e021 is a dev drive fault in the service manual.

Any ideas anyone please much appreciated

thanks

If u have the POD DECK A1- u can use Coated paper
If u have the Paper Deck Unit= u can not use Coated paper

Multi Draw Deck=Coated is OK to use

Stack Bypass = single sheet feed only for Coated

imageRUNNER ADVANCE C E021-0101 / sharp lines and noise


In the field, E021-0x01 was displayed due to coupling failure of the Developing Assembly. In this field case, the error occurred in the Yellow Developing Assembly.

Sharp lines in horizontal scanning direction at 37mm intervals (corresponding to one turn of the Sleeve) accompanied by a sound of teeth being disengaged may also occur.

- E021-0x01: Developing Sleeve Drive Motor error (x=1:Y, 2:M, 3:C, or 4:Bk)


Solution :
When the Process Unit was installed in the main body, the Developing Assembly and the coupling of the main body were not properly engaged, which caused overload on the Developing Sleeve Drive Motor and resulted in the error.

Field Remedy
Remove the Process Unit of the color where the error occurred, and check the mold next to the coupling of the Developing Assembly for damage.
- If there is any damage: Perform step A. (The error was caused by coupling failure.)
- If there is no damage: Perform step B. (The error was not caused by coupling failure.)



A. Rotate the coupling of the Developing Assembly 45 degrees counterclockwise. Then, return the Process Unit to the main body.



Note] Be sure to rotate the coupling counterclockwise.

B-1. Check the connection between the Developing Sleeve Drive Motor and the DC Controller Interface PCB (UN2).
- Bk motor (M18): J7538, J8243 PCB: J8236, J1227
- Y motor (M20): J7535, J8034 PCB: J1220
- M motor (M22): J7536, J8034 PCB: J1220
- C motor (M24): J7537, J8034 PCB: J1220
B-2. Replace the Developing Assembly where the error occurred.
B-3. Replace the DC Controller Interface PCB (UN2).
B-4. Replace the Developing Sleeve Drive Motor.

E 021 0x01

Thanks for the info i'll get my tech to check these units.

But there is this issue of the POD deck A1 the E021 error only occurs when printing from that unit, if you run the prints from any other paper cassette then it works fine.

A bit of a strange one just wondering if there is either a major fault with the deck spiking the copier somehow or when printing coated stock from the deck the copier is failing under a certain set of conditions causing the dev drive to fail , which i find highly unlikely..think i'm clutching at straws !

need to look into that only on POD Deck A1 E021 issue/ will call friend in Canon Engineering

E021-0X02/ READ BELOW/ could apply for any color= 0102-0202-0302-0402
August 12, 2010 imageRUNNER ADVANCE C7065 / C7055 / C9065 PRO / C9075 PRO Error Code E021-0202
Code occurs during initial rotation and always has the same sub-code.


In this case, the magenta drum shaft, magenta drum drive motor, and magenta developer drive motor were removed and reseated to resolve the error code.

...We have already had to replace magenta & yellow due to rear of devs starved of dev...

Since it is a new install, did you check that the copier is level? It's rare but we see that evry now and then. More on color sine the toner is much finer and yellow flows almost like a liquid.

hi thanks for reply

pretty sure the copier is level its in a new office environment and its replaced a C1 they had there for 2 years .
Its worth looking at though, but it still this issue it only happens when you print from the
A1 pod deck , its ok printing from any other cassette port.

Just to clarify the issue>
Plain paper used in Cassettes & Deck will not cause a E021 ??

Registered Coated paper used in POD Deck > will cause E021 ??
*****Coated must be registered for Deck*****

Have u tried Coated paper in Bypass Tray [single sheet feed only] ?

[worthy67]

Hi
plain paper and other types of stock work , also if he puts coated in the paper cassetts it works but that said i thought you couldnt put coated stock through the cassettes so i think my engineer put it through has heavy 2.
I will find out if he tried coated throught the bypass.

See i'm wondering if its the fact that coated stock is being selected that is causing the problem.
Canon have agreed to D.O.A the pod deck but i'm not so sure its the cause of the problem.

[teckat]

I would not run/push coated stock in cassettes by selecting Heavy 2

did the customer register Coated Paper for DECK ?

[worthy67]

Hi

i know i agree its not really a good idea , we just did it for pocess of elimination .

The deck is registered for coated stock ,it switches on fans that improve separation of the coated stock.
personally i dont think it is the deck at fault . i think its when coated stock is selected.

[teckat]

Do u receive a JAM code on Deck/ when printing coated paper ?
or a straight E021 ?

[charm5496]

I you only have the paper deck attached to this unit then you still have the stack bypass door on the machine. Why don't you properly register that stock in question to see if you get the errors when running it there. Also have you tried running any other stocks from the paper deck to see if they give you similar issues?

Has firmware been reloaded or upgraded on this unit? I would do a complete overwrite of all data in this unit. I have had too many situations where different levels of firmware have caused issues that would make you scratch your head.
Let us know what you find.

hi guys

our engineer went back to try some more things at the request of Canon

We tried coated stock through the bypass with the relevant stock settings
and it still threw the E021 0101 error we even swapped the dev motors and the
fault code stayed the same .
All seems fine if you select heavy 2.
even changed function /common settings /printer settings/coated stock to productivity from quality.

???
When does this code appear ??
1- when u hit the print key ?
2- when u send a job from network/ PC or MAC ?

3. Is paper picked up at all in DECK/ or Bypass ?

No delay jam codes- only an E021 ?

The fact that it happens from BYPASS & DECK when u select COATED, COULD POINT TO A Firmware Glitch.
